Show HN: DroidPutter – Run Cardputer Apps on Android via USB OTG

Category: devtools

Tags: esp32, android, usb-otg, firmware-flashing, cardputer, hardware-bridge

Score: 7.0/10 (Innovation: 8, Technical: 8, Documentation: 7, Utility: 5)

Droidputter turns an Android phone into a display, keyboard, GPS, and flasher for open-source Cardputer apps running on an ESP32-S3 over USB OTG. It rebuilds Cardputer apps on demand from GitHub against a display/keyboard shim, flashes them from the phone, and mirrors the app screen on the phone. The project is an inventive hardware-software bridge that eliminates the need for a dedicated Cardputer display while breathing new life into a niche ecosystem.

Target audience: Embedded developers, hardware hackers, and Cardputer enthusiasts
